Title: Hot air circulation type kiln
Inventor: KAGEYAMA TETSUYA
IPC: F27B3/02
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the burning of a dust filter and enable the baking of work at a temperature higher than the heat resistant temperature of said dust filter, by installing a heating means which reheats an ambient gas in a circulation passage where the ambient gas must circulate until it reaches the work after it has passed through the dust filter, and a cooling means designed to cools the ambient gas which has heated the work in the circulation passage. CONSTITUTION:The dust contained in an ambient gas is removed by heating the ambient gas and allowing said heated ambient gas to pass through a dust filter 5. After the dust removable, the gas is further heated up to a high temperature, say, around 500 deg.C. The high temperature ambient gas is arranged to blow to work W, which is transferred by a work transfer conveyer 7 so that a work W may be baked at a temperature high than the heat resistant temperature (about 300 deg.C) of the dust filter 5. The high temperature ambient gas which has baked the work W is mixed with and cooled by a cooling air supplied from a cooling means 8 and sent again to a preheater 4 by a circulation fan 3. It is, therefore, possible to heat work at a temperature higher than the heat resistant temperature of the dust filter without burning said filter and perform high temperature baking of work in very clean atmosphere.

Title: Time sheaking multiple control system
Inventor: FUJIMURA NORIAKI
IPC: H04J3/16
Filed: 1978-08-31
Abstract: PURPOSE:To ensure a high-efficiency multiplication as well as to secure an easy decision at the reception side for the slot allotment process at the transmission side for the time shearing multiple control system with which the idle time and slot are allotted when the transmission requests are given from terminal circuits of different transmission velocities. CONSTITUTION:The time slot on the circuit forms one frame shown in A and then allots previously slot T0 to channel CH0 like CH1 against the terminal of 50BPS like B. For the terminal of 100BPS, T0 and Tn plus T1 and Tn+1 are allotted to CH0 and CH1 respectively. In case the data transmission requests are given at one time from several units of terminal circuits, the request from only one terminal is made effective based on the expected priority sequency with other requests put under the holding state. The indication signal is provided to the idle CH, and the idle CH allotted by occurrence of the transmission signal request receives the transmission start indication signal (one signal row) instead of the idle state signal (zero signal row). Thus the reception side recognizes the allotment state based on the signal change.
